To all w/zom it may concern:

Be it known that I, lliuur A. DOUGLAS, citizen of the United States, residing at Bronson, in the county of Branch and State of Michigan, have ini'ented a certain new and useful Improvement in Reflecting Lamps, of which the following is a full, clear, concise, and exact description.

My invention relates to reflecting lamps of the so-called spot light variety and has a number of objects and advantages in view.

In tlCLOltlitllCQ with one characteristic of my invention the reflector, the retaining rim for holding the light transmitting cover in assembly with the reflector and the handle are integrally formed out of material. This handle is made hollow with its interior merged with the interior of the reflector and the light source is contained in the handle in the front portion thereof, this second feature of my invention being preferably embodied in the same construction in which the cover retaining rim is integrally formed with the reflector and handle.

In accordance with another feature of the invention the handle which may be connected with the reflector or reflector carrying casing in any suitable way, is reduced at its forward end Where it joins the casing to form neclt. In thisnecl; the light source of the lamp may be disposed and about this neck the lamp supporting bracket may be secured. In an electric lamp structure the formation of a neelr in the forward portion 7 of the handle is of material advantage since such a construction permits, of the ready adjustment of the lamp bulb, in focusing,

and also permits of the read adaptation of switching mechanism in the shell and the dis-.

positionoi' current carrying conductors in the rear of the light source.

These and other characterlstics of my invention will be fully set forth by reference to the aecompmrvnig drawings showing the preterm-(l embodiment of the invention and in "which Figure l a side elevation, pai tially in section, of a reflecting lamp containin features of my invention; Fig. 2 is a longitudinal View, partially in section and partially in elevation, of portions of the structure illustrated in Fig. 1; Fig. 3 is a. view on line 33 of Fig. 4; and Fig. l is a view on line l-4 of Fig. 1'.

Like parts are indicated by similar characone piece of 7 side margins to permit it freely to function.

Some part of the tongue, such as the rear free end thereof, has a part 6 projecting therefrom which is narrower than the balance of the tongue and slightly nar rower than a slot 7 in the holder 3 whereby this portion may project into the slot to prevent the shell from turning with respect to the slot while at the same time the side margins of the tongue l are adapted to press against the side margins of the slot 7. The tongue thus presses upon a surface of the holder 3 and, Where there is but one tongue, forces the shell toward the opposite side of the holder whereby the shell is held in engagement with the holder 3. The slot 7 is elongated so that the shell 5 may be moved back and forth in its holder 3 whereby in the structure illustrated the position of the lam bulb 8 which is carried by the forward end of the shell in front of the reflector may be adjusted with respect to the reflector. The base 9 of the lamp bulb 8 constitutes the forward contact carrier and as the arrangement illustrated is a double )ole arran 'einent this contact carrier 9 carwas two rear contacts 10 tllld 11. The lamp base or contact carrier 9 is provided with bayonet pins 1'2. engageable Within bayonet seats 13 constituting parts of bayonet slotsm the m "ml in which spa a conductors m3 when switching mam. 9 ran f b5 01- ved that whiz handy: and the 1e am it may pa rfimr are fen d inta ndly out 0 2 tha same of 11121011211, pram-ably mm! fcmnmi i211") the iequisite shay), 7;;
